Title: Ignition timing control device for internal combustion engine
Inventor: WATANABE KENJI
IPC: F01L13/00
Filed: 1991-12-24
Abstract: PURPOSE:To prevent transitional generation of excessive delay or excessive advance in ignition timing in connection with an ignition timing control device for an internal combustion engine having a variable valve timing mechanism (VVT) when both control for switching the valve timing and control for switching the ignition timing are performed. CONSTITUTION:The spark advance correction amount (a) for each ignition period is determined by dividing the difference DLABSE between a spark advance map value ABSE 1 at the time of VTT-off and a spark advance map value ABSE 2 at the time of VVT-on by the ignition frequency (f) during operation of the VVT. In the routine starting for each ignition period, the ABSE is renewed by subtracting (a) from the ABSE at which an initial value of the ABSE 1 is set, and a practical spark advance ABSE is gradually spark advance- corrected from an initial value or the ABSE 1 to the ABSE 2 to the time until the operation of the VVT is completed. Thus, transitional excessive delay or excessive advance of the ignition timing can be prevented.

Title: Packet repeating control method and packet repeater
Inventor: YAMAMOTO HIROYUKI
IPC: H04L45/16
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To reduce the unnecessarily repeating of conversion request packets occupying a large ratio in a broadcast frame and to improve the traffic of an extension local area network(LAN) and the throughput of a packet terminal. SOLUTION: The respective ports of a bridge receive and transmit frames with a respective LAN. A learning processing part 14 monitors the frames from the respective ports and learns the relation of a transmission source packet terminal and the port. A database 15 stores the set of a terminal address, a port number and a protocol address of the transmission source obtained by the learning. Based on the database 15, a transfer processing part 16 and a broadcast processing part 18 respectively repeat and abandon the respective frames of non-broadcast and broadcast. When a conversion request packet to be broadcasted is received and the database 15 stores its data transmission destination protocol address, the latter part 18 repeats the conversion request packet only to the port being a set with this address and does not repeat it to the other port.

Title: Method of manufacturing wiring board
Inventor: KASHIWAGI TETSUYA
IPC: H05K3/46
Filed: 1999-12-01
Abstract: PROBLEM TO BE SOLVED: To prevent recesses from being formed in through-holes formed in a board to be filled or voids from growing in vias due to flowing of a resin paste into the vias when the resin paste is heated to harden in a step of filling the through-holes with the resin paste. SOLUTION: Via conductors 9 having a plating metal filled in the vias are formed previously in the board to be filled, the board having the through-holes 7 and the vias 8. Owing to this, the resin paste never flows into the vias when the resin paste 13p is filled in the through-holes 7, thus preventing the recesses from being formed in the through-holes or voids from growing in the vias. Via conductors 19 may be connected on the via conductor 9 and hence a high density wiring is possible.

Filed: 1989-12-28
Abstract: PURPOSE:To obtain the title epoxide compatible with another polymeric compound without detriment to its mechanical strengths by oxidizing a macrocyclic polyolefin having a specified molecular weight and regularly arranged double bonds. CONSTITUTION:A macrocyclic polyolefin having a number-average mol.wt. of 30000 or more and regularly arranged double bonds, at least one per eight carbon atoms (a 250-membered or larger cyclic polyolefin obtained by the metathesis polymerization of, e.g. cyclopentene or cyclooctene in the presence of a tungsten catalyst, especially WCl6, and a cocatalyst) is oxidized (e.g. by treatment with H2O2) to obtain a macrocyclic polyolefin epoxide. This epoxide is excellent in compatibility with another high molecular polymer and dispersibility therein, and therefore even when mixed with another polymer, it is not detrimental to the strengths but can improve them further. It can be readily reacted with a low-molecular compound or a high molecular compound. Therefore, it is useful as a modifier for a high molecular polymer or a material reactive with a low molecular compound or a high molecular compound.

Title: Wave absorbing body for tv frequency band
Inventor: YAMAMOTO TAKESHI
IPC: H05K9/00
Filed: 1989-12-29
Abstract: PURPOSE:To realize a wave absorbing body which can be formed easily and can absorb a wide band range of TV waves by setting the peak value of the imaginary part of the complex permeability of the body formed mainly of cement and a magnetic granular substance mixed with each other at a specific dry weight ratio to a level lower than the frequency band of TV waves. CONSTITUTION:The peak value of the imaginary part of the complex permeability of a formed body composed mainly of cement and a magnetic granular substance mixed with each other at a dry weight ratio of 10-25 : 75-90 is set to a level lower than the frequency band of TV waves. When the mixing ratio of the magnetic powder is increased, the imaginary part becomes higher and the ratio of the real component to the imaginary part becomes smaller. Accordingly, when the thickness and absorbing characteristics of this absorbing body is taken into account, the mixing ratio of the magnetic granular substance is adequate within the above mentioned range. Thus a wave absorbing body which can be formed easily and can absorb a wide band range of TV waves is obtained. In addition, the wave absorbing characteristics of this body can be finely adjusted by adding carbon fibers by 0.01-1.0%.
